Cardiac performance is typically assessed measuring ventricular volumes using Simpsons rule, over short axis cine MRI scans. Heart functional indexes, such as end-systole volume, end-diastole volume or stroke volume, are usually computed from manual segmentations performed by an expert. This process is tedious and time consuming. We proposed a method based on Level Sets with preserved topology that allows to segment the left and right ventricles simultaneously without increasing the computation time, nor using any training data, and requiring minimal human intervention. Bland Altman analyses showed that our method has an excellent agreement with manual segmentations.
